Embodiment Construction

[0035] Assembly method of the present invention: as figure 1 As shown, the pneumatic piston-driven lift pump consists of an airflow pulse generating device (A) and an airflow injector (B).

[0036] In the pulsed air flow generator (A), the rectifier disc (7) is closely attached to the outer shell (8) through bolts; the air distribution static disc is tightly connected to the outer shell (8) through bolts; Connected with the rotating shaft (4) through a flat key, it can rotate together with the rotating shaft; in order to reduce the gas leakage between the gas distribution disc and the gas distribution static disc, a sealing disc is embedded in the pit on the right side of the pneumatic disc, and the sealing disc has the same The exhaust hole structure is the same as that of the pneumatic disc, and its material is polytetrafluoroethylene; the center holes of the rectifier disc (7) and the static disc (11) are respectively equipped with rolling bearings (3), and the inner rings...

Abstract

The invention discloses a pneumatic piston push type lift pump. The pneumatic piston push type lift pump comprises an airflow pulse generation device and an airflow injector. Through holes are formedin a gas distribution movable disc and a gas distribution fixed disc, the two gas distribution discs are closely attached to each other, a rotating shaft drives the gas distribution movable disc to rotate, and the through hole effective flow area between the gas distribution movable disc and the gas distribution fixed disc is continuously changed, so that pulse modulation is carried out on continuous airflow, and the modulated airflow is injected into an upper pump body through the airflow ejector to form intermittent gas-liquid two-phase flow. According to the lift pump, through airflow pulsemodulation, continuous airflow crushing in a pipe is promoted, an intermittent flow structure of bubbles and a liquid column is formed, a strong bubble piston pushing effect is induced, the drag force of the airflow is effectively enhanced, and the working performance of the pneumatic lift pump is greatly improved.

Description

technical field [0001] The invention relates to the technical field of lift pumps, in particular to a pneumatic piston-driven lift pump. Background technique [0002] The vast ocean is a huge treasure house of resources owned by human beings. The deep seabed area contains mineral resources far exceeding those on land. Among them, 70 billion tons of polymetallic crust resources can be mined, about 21 billion tons of cobalt-rich crust resources, and the amount of rare earth resources on the seabed is 800 times that of land. In the development of marine resources, equipment technology is the key. In view of the extreme environment and special state of occurrence of deep-sea mineral resources, it is extremely critical to transport seabed mineral resources at a depth of several thousand meters to the sea surface. Countries all over the world are vigorously developing efficient and pollution-free mineral lifting technologies. As one of the effective tools for mineral lifting, th...
